Abstract
A DC--DC power converter circuit for converting relatively high input voltages to relatively low output voltages employs a buck-type circuit topology with a multiple winding inductor. An optional winding is provided to the inductor to clamp a voltage spike appearing on the drain of one of the switching devices. Optionally, two inductor windings may be capacitively coupled for better efficiency.
